Controller. The cable has distinct connections that will only mate in the
proper manner.

time the LCD displays a countdown to completion and the lighted
indicator closest to the Probe Tip is orange (See Figure 2-2) until the
following operations complete:
• Heat the Wide Range Sensor® to operating temperature.
• Perform system self-test.
• Zero the sensor reading.
